HPSC stability control
Purpose of HPSC
PALFINGER's High Performance Stability Control system (HPSC) is an electronic system that monitors
the stability of vehicles with loading cranes.
Benefits for the operator
Note!
When equipped with HPSC, loading cranes are stable even if the
vehicle's stabilizer cylinders and outrigger beams are only partly or
not extended / used.
This makes it possible to work safely with the loading crane even in
narrow areas.
Function
The HPSC system is based on an a real time computation of the vehicle's actual stability taking the
current positions of the stabilizers into account. As a result a lifting power limit curve is produced which
covers the entire slew range and comes close to the actual vehicle stability.
